BACKGROUND: Prior trials comparing a strategy of optimal medical therapy with or without revascularization have not shown that revascularization reduces cardiovascular events in patients with stable ischemic heart disease (SIHD). However, those trials only included participants in whom coronary anatomy was known prior to randomization and did not include sufficient numbers of participants with significant ischemia. It remains unknown whether a routine invasive approach offers incremental value over a conservative approach with catheterization reserved for failure of medical therapy in patients with moderate or severe ischemia...

INTRODUCTION: A rising incidence of kidney stone disease has led to an increase in ureteroscopy (URS) and shock wave lithotripsy (SWL). Our aim was to compare the cost of URS and SWL for treatment of stones. METHODS: A systematic review and meta-analysis based on Cochrane and PRISMA standards was conducted for all studies reporting on comparative cost of treatment between URS and SWL. The cost calculation was based on factual data presented in the individual studies as reported by the authors...

INTRODUCTION: Nephrolithiasis is one of the most common diseases in urology. According to the EAU Guidelines, a percutaneous nephrolitholapaxy (PNL) is recommended when treating a kidney stone >2 cm. Nowadays PNL is performed even for smaller stones (<1 cm) using miniaturized instruments. The most challenging part of any PNL is the puncture of the planned site. PNL-novice surgeons need to practice this step in a safe environment with an ideal training model. We developed and evaluated a new, easy to produce, in-vitro model for the training of the freehand puncture of the kidney...

despite fluctuations, the prevalence of nephrolithiasis has significantly increased during the last decades in industrialized nations worldwide (1 to 15 %), which has a significant impact on the cost of healthcare. This increased prevalence is mainly explained by diet modifications. Environmental, metabolic and genetic factors may also influence the formation of kidney stones. As a consequence, the medical management of this disease is preferentially multidisciplinary and involves urologists, nephrologists, radiologists, biologists and dietitians...

PURPOSE: Recent reports support renal ultrasound as the initial imaging study to evaluate patients with suspected renal colic. However, urologists often advocate for computerized tomography to better define stone size and location, especially before proceeding with endourological intervention. One concern with using ultrasound as initial imaging is that computerized tomography may be required later, obviating the reduction in costs and radiation gained by using ultrasound. MATERIALS AND METHODS: We retrospectively reviewed the electronic health records of 10,680 episodes of stone disease in a total of 7,659 patients who presented to the emergency department or walk-in clinic with a chief complaint or visit diagnosis of urolithiasis from 2009 to 2015 at a single institution...

The rising prevalence of kidney stone disease is associated with significant costs to healthcare systems worldwide. This is in part due to direct procedural and medical management costs, as well as indirect costs to health systems, patients, and families. A number of manuscripts evaulating the economics of stone disease have been published since the 2008s International Consultation on Stone Disease. These highlight costs associated with stone disease, including acute management, surgical management, and medical management...

OBJECTIVES: Symptomatic ureterolithiasis (renal colic) is a common Emergency Department (ED) complaint. Variation in practice surrounding the diagnosis and management of suspected renal colic could have substantial implications for both quality and cost of care as well as patient radiation burden. Previous literature has suggested that CT scanning has increased with no improvements in outcome, owing at least partially to the spontaneous passage of kidney stones in the majority of patients...

Diabetes and obesity are already recognized as potential risk factors for nephrolithiasis, especially for uric acid stones. Insulin resistance and hyperinsulinemia actively contribute to impaired ability to excrete an acid load and altered ammonium production, leading to a lower urinary pH compared to non-diabetic controls. All these electrolytic disorders play an important role in stone formation and aggregation, especially in uric acid stones. There are still missing points in scientific evidence if the increased risk in stone formation is already existing even in the prediabetic statuses (isolated impaired glucose tolerance, isolated impaired fasting glucose, and associated impaired glucose tolerance/impaired fasting glucose) as well as it is worth to consider the same level of risk...
